Week 15 brings us to the MLB All-Star break which puts the fantasy season on a brief four-day hiatus in terms of games being played. This also creates an opportunity to jump on some guys who may be floating around your waiver wire that the other owners in your league aren’t paying attention to because games are not being played.  With that being said let’s take a look at some of the best available players that could be in your league's free agent pool.

Catcher

10-Team League

J.T. Realmuto, MIA – Realmuto enters the All-Star break hitting .317 with 34 runs, five home runs, 26 RBI and nine stolen bases which is good enough to have him ranked as the fourth-best catcher in fantasy.  Despite his rankings and production Realmuto finds himself owned in under 70 percent of standard leagues which is just mind boggling.  Do yourself a favor and pick up Realmuto if he is on your waiver wire because unless you have Buster Posey or Wilson Ramos it’s unlikely you can do much better at the position.

12-Team League

Stephen Vogt, OAK - Vogt was named to his second straight All-Star game on the heels of a first half which saw him hit .277 with 30 runs, seven home runs and 27 RBI which is good enough to have him ranked as the 10th best catcher and fantasy in most league formats.  Vogt is currently owned in 60 percent of standard leagues so check your waiver wire if you are in need of an upgrade.

15-Team League

Yasmani Grandal, LAD - Grandal has the talent to be a starting catcher in all league formats but a very sluggish first half saw his ownership levels drop significantly.  He is currently owned in just 15 percent of standard leagues but that number is on the rise as he is hitting .440 with five home runs so far in the month of July.  Grandal is certainly worth grabbing given his upside as a low risk stash given how shallow the catcher position can be at times.

First Base

10-Team League

Carlos Santana, CLE - Santana heads into the All-Star break hitting .253 with 52 runs, 20 home runs, 49 RBI and four stolen bases.  His production is good enough to have him ranked among the top 10 first basemen in fantasy.  Santana is an OBP machine that has always shown good power but struggled with his batting average due to a low BABIP. However, this season his BABIP is improving thanks to a solid hard contact rate which could put him online for a career year.  Santana is owned in about 80 percent of standard leagues so check the waiver wire because he’s worth having on your roster.

12-Team League

Mike Napoli, CLE - Napoli has been on this list a few times this season as he enjoys a solid first year in Cleveland which he is hitting .243 with 54 runs, 18 home runs and 61 RBI.  Napoli is owned in just over 50 percent of standard leagues but ranks among the top 10 first basemen in fantasy to this point in the year.  Napoli is not going to win you any batting titles but his power and RBI production makes him certainly worth rostering.

15-Team League

Tommy Joseph, PHI – The Phillies rookie enters the All-Star break hitting .255 with 22 runs, 11 home runs and 21 RBI.  Leading up to the All-Star break Joseph had homered in three of his last five contests which gives you an idea of his power upside.  He is currently owned in just 5 percent of standard leagues so for those in deeper mixed and NL-only leagues Joseph can help provide some home run potential to your roster.

Second Base

10-Team League

Jonathan Schoop, BAL - Schoop enters the All-Star break on pace for a career year as he is hitting .304 with 49 runs, 14 home runs and 52 RBI for the Orioles.  He is currently ranked sixth among fantasy second basemen in most standard league formats yet is available in nearly 25 percent of leagues.  Second base is not nearly as shallow as it used to be but for somebody showing this level or power along with a batting average deserves to be on more rosters.

12-Team League

Danny Espinosa, WSH - Espinosa’s production has started to taper off a bit over the last week but it’s hard to ignore the surge that vaulted him towards the top 10 fantasy second basemen. He enters the break hitting .239 with 41 runs, 18 home runs, 49 RBI and five stolen bases.  As long as he continues to hit, the Nationals will play him every day which will give Espinosa a good shot at setting a career high in home runs while notching double-digit stolen bases.  He is currently owned in just over 50 percent of standard leagues so check the wire and if you need an upgrade at the position I would pick him up.

15-Team League

Javier Baez, CHC – The Cubs are committed to getting Baez in the lineup as they have played him all over the diamond this season and he is enjoying a solid season because of it as he enters the break hitting .273 with 28 runs, nine home runs, 30 RBI and six stolen bases.  Baez is owned in just under 40 percent of standard leagues but has already gained position eligibility at third base, second base and shortstop which only adds to his value.  He is a lock for double-digit home runs and steals so in deeper league formats he is certainly worth adding given his upside.

Shortstop

10-Team League

Eduardo Nunez, MIN - Nunez is currently ranked among the top five shortstops in fantasy this season yet is owned in just over 80 percent of leagues.  The first-time All-Star enters the break hitting .321 with 46 runs, 12 home runs, 40 RBI and 22 stolen bases for the Twins. He finds himself on pace to flirt with a 20-home run and 30-stolen base season which is fairly rare to see these days never mind having it come at the shortstop position.  Check the wire and if Nunez is there go and pick him up.

12-Team League

Jose Reyes, NYM – Reyes has made quite the impression in his brief stint back with the Mets, hitting .250 with five runs, three home runs and three RBI.  Five of his six hits have gone for extra bases as he is showing fantasy owners that he still has some power left in his bat.  Reyes should still have some stolen base ability left as well, seeing as he grabbed 24 bags last season.  He is owned in just under 30 percent of standard leagues so if you find yourself in need of an upgrade at shortstop or middle infield his upside makes him worth grabbing.

15-Team League

Marcus Semien, OAK – Semien could just as easily be owned in 12-team leagues as well seeing as he enters the All-Star break hitting .242 with 42 runs, 19 home runs, 47 RBI and five stolen bases.  His 19 home runs has him tied for second among shortstops in baseball.  He is currently owned in just 35 percent of standard leagues but he is easily going to eclipse the 20-home run plateau and has the ability to swipe double-digit stolen bases given the 11 he stole last season.  Semien is currently the 15th rank shortstop in fantasy this season so if you need an upgrade or some power at your middle infield spot he’s worth a grab.

Third Base

10-Team League

Jake Lamb, ARI - Lamb is owned in just over 80 percent of standard leagues despite ranking among the top five third basemen in fantasy. He enters the All-Star break hitting .291 with 40 runs, 20 home runs, 61 RBI and three stolen bases.  Lamb was having a breakout season in 2015 before an injury derailed him but with better health and another season under his belt he is proving to be one of the leagues breakout players.  Lamb should be owned in all formats but seeing as he is available in nearly 20 percent of leagues I would check your waiver wire and see if you can grab him.

12-Team League

Luis Valbuena, HOU - Valbuena is currently the 17th ranked third basemen in fantasy but he is quickly climbing the ranks thanks to an impressive stretch of play dating back to May beginning of May which sees him hitting .295 with 31 runs, 12 home runs and 33 RBI over his last 59 games.  The power potential with Valbuena is real and if he can continue to hit for a decent average he should have little trouble approaching the top 10 at the position.

15-Team League

Yangervis Solarte, SD – Solarte has seen his ownership nearly double since last week as the Padres' third baseman heads into the All-Star break hitting .295 with 25 runs, eight home runs and 35 RBI.  Over the last two weeks, however, he is hitting .353 with nine runs, four home runs and 13 RBI which has caused fantasy owners to take notice.  Solarte is eligible to play first, third and second base which only adds to his overall value.  He is worth owning in most 12-to-15 team formats and is a must own in NL-Only leagues.

Outfield

10-Team League

Melvin Upton Jr., SD – I don’t know what else to tell you at this point other than to believe in Melvin Upton Jr. and your fantasy team will be better.  He is currently the 12th ranked outfielder in all of fantasy yet is owned in just 65 percent of leagues because of how skeptical people are that he can keep it up.  He enters the All-Star break hitting .262 with 45 runs, 16 home runs, 44 RBI and 20 stolen bases which put him on pace to hit nearly 25 home runs while swiping 30-plus stolen bases.  Check your waiver wire and if Upton is available I suggest swallowing your pride a bit and put him on your team because the numbers don’t lie.

12-Team League

Shin-Soo Choo, TEX – Choo just keeps on hitting since returning from the disabled list and enters the All-Star break hitting .274 with 22 runs, seven home runs, 17 RBI and four stolen bases.  Over the last two weeks, Choo has been even better, hitting .310 with 11 runs, four home runs, nine RBI and one stolen base. He is currently owned in 65 percent of standard leagues so check your waiver wire as Choo offers the power and stolen base upside that fantasy owners covet.

15-Team League

Randal Grichuk, STL– Grichuk was a popular sleeper pick coming into the year after his impressive 2015 which saw him hit .276 with 49 runs, 17 home runs, 47 RBI and four stolen bases.  Unfortunately, he was not able to find that same magic and was ultimately demoted.  The upside is still present, however, and the Cardinals just recalled Grichuk from the minor leagues.  In the seven games leading up to the All-Star break Grichuk hit .409 with three runs, two home runs and four RBI.  He is owned in 25 percent of standard leagues and in deeper formats as well as NL-only he is worth stashing just in case he turns in a solid second half.

Starting Pitchers

10-Team League

Drew Pomeranz, SD – Pomeranz was named to his first All-Star team thanks to an impressive first half which he went 8-7 with a 2.47 ERA while striking out 115 over 102 innings.  His first start out of the All-Star break is expected to come on Sunday against the Giants who he has held to just two runs over 13 innings so far this season.  Pomeranz is owned in just over 80 percent of standard leagues but is a top-10 starter and is a must own.

12-Team League

R.A. Dickey, TOR – Dickey enters the All-Star break going 7-9 with a 3.93 ERA, 1.29 WHIP and 83 strikeouts over 116.2 innings. While those numbers are relatively average he has actually been pitching much better for nearly two months, going 6-6 with a 3.10 ERA over his last 14 starts. The Blue Jays have not set their rotation yet for when they come out of the break so we don’t know who Dickey will be facing next but it will be either the A’s in Oakland or the Diamondbacks in Arizona.

15-Team League

Anthony DeSclafani, CIN - DeSclafani enters the All-Star break going 3-0 with a 2.23 ERA while striking out 29 over 36.1 innings.  He has earned quality starts in five of his six starts since coming off the disabled list and just held the Cubs to three runs over six innings which is no small feat.  He will start for the Reds on Friday coming out of the break in a home contest against the Brewers.  DeSclafani is owned in under 50 percent of standard leagues but is worth a pick up as a spot starter and a potential back-end fixture in your fantasy rotation.

Closers

10-Team League

Jonathan Papelbon, WSH – Papelbon has notched saves in three of his four appearances since coming off the disabled list while allowing just one hit and striking out eight over four innings of work.  He is owned in 85 percent of standard leagues but is still one of baseball’s top closers even at his age and deserves to be owned like one.

12-Team League

Koji Uehara, BOS – With news that Craig Kimbrel is going to miss up to six weeks due to knee surgery the Red Sox went out and traded for Brad Ziegler but have decided to give Uehara the closer's job.  He has responded by picking up a save in each of his last two appearances.  It has been a tough season for Koji as he transitioned into a set-up role but he might find success once again in a role that he has thrived in for the past few years.

15-Team League

Tyler Clippard, ARI – With Brad Ziegler getting traded to Boston, the Diamondbacks are expected to use Clippard as their new closer.  Clippard has 54 career saves which included notching 17 saves for the A’s last season before being traded to the Mets and used as a set-up man.  Clippard's best season came in 2012 when he saved 32 games for the Nationals.
