When Albert Pujols launched a Bartolo Colon fastball over the fence in Tuesday’s win over the Braves, the 37-year old slugger took one more step towards baseball immortality. Already a lock to be a first-ballot Hall of Famer, Pujols smacked his 599th career home run and will now spend his next however many games chasing the dream of being just the ninth major leaguer to reach the 600-homer mark and join the ranks of Barry Bonds, Hank Aaron, Willie Mays, Babe Ruth, Alex Rodriguez, Sammy Sosa, Ken Griffey Jr. and Jim Thome. There’s no doubt that Pujols will reach the milestone soon enough, but the obvious question on everyone’s mind is, “When?”

Maybe he’ll end the suspense tonight and take Braves’ starter Jaime Garcia deep, but it got me to wondering just how much these guys think about their milestones and whether or not chasing these numbers is actually detrimental to their overall game. Even the most-focused of players can’t help but see the milestones posted across the scoreboard at the stadium and if they go home and watch Baseball Tonight or Quick Pitch, they’re obviously inundated by the talk of reaching such historic levels. Does it stay on their mind? Do they get wrapped up in their heads about it when stepping up to the plate?

When A-Rod clubbed his 599th homer, he went 13 games (47 at-bats) without going deep before finally connecting for his milestone shot. Griffey entered the 2008 season with 593 homers and it took him 216 at-bats to reach No. 600 which came 17 at-bats after his 599th. On the other hand, Craig Biggio wasted no time picking up his 3,000th hit as he was sitting on 2,997 before a masterful five-hit game saw him reach his immortality in the seventh inning, his third hit of the game. Derek Jeter connected for his 3,000th (a home run at that) while on a four-game hit streak in early July of 2011. Even Barry Bonds needed just eight at-bats between No.’s 599 and 600.

For some guys, it’s just routine. They do what they do and try not to think about it. For others, it might be a little more than that. It would be tough to go through every milestone moment in the history of baseball and track how long it took each player to reach the pinnacle, but we can look forward here in 2017 and see which players are about to reach a certain historic plateau. Watching players on your fantasy team chase the record books is often an exciting thing, but watching them get stuck and put up doughnuts for your team while they get out of their heads can definitely be frustrating, especially since we’re often talking about aging superstars with declining skills or, in some cases, over-anxious youngsters who could be more susceptible to mental blockages as they approach their personal records.

Here's a look at some of the milestones we are hoping to see reached this year and whether chasing the dream is going to be good for fantasy owners:

Albert Pujols – 600 HR

Pujols is hot at the plate right now and not only is he sitting on a six-game hit streak, but he’s gone yard in back-to-back games now which gives him three homers in his last five games. Though he’s missed some time due to minor injuries, it had only been eight games between home run No. 596 and 597 and just two games between 597 and 598. He’s locked in at the plate, but also sits as a man alone on an island with Mike Trout now on the disabled list. While we’d like to just see him cruise through this series against the Braves and put the record behind him, it also wouldn’t be too surprising to see pitchers try and work around him rather than go down in the record books as the guy who served up Albert’s career-defining moment.

Adrian Beltre – 3,000 hits; 600 doubles

Having finally returned from a lengthy stay on the disabled list with a calf injury, Beltre is ready to get back into the swing of things, literally, and start advancing towards MLB history. With his sixth-inning double in Tuesday’s game, Beltre is now 56 hits away from reaching 3,000 hits and just eight doubles away from reaching 600. The doubles milestone might not seem all that impressive, but according to Baseball Reference, there are only 16 who have done it in the history of majors. The big question for Beltre will obviously be health, but after watching him leg out that double Tuesday, the calf looks good and he should be ready to roll.

Carlos Beltran – 450 HR

Not the sexiest milestone, but Beltran is obviously looking to separate himself from the 400-homer pack and get as close to the 500 threshold as he can. Having already smacked six homers this season, Beltran needs just 23 to reach 450 which will put him just inside the top-10 among those in the 400-homer club. At 40 years old, it’s tough to see him advancing much beyond that, though as a full-time DH, he’s could certainly be given the opportunity by someone. He’ll have to pick his game up significantly though, as most, if not all of his numbers are in decline this season, from strikeout rate to OBP to isolated power. You can probably still squeeze some productivity out of him while he chases this personal milestone, but he’s really no more than a fifth or sixth outfielder on fantasy teams these days.

Miguel Cabrera – 1,000 extra-base hits

Cabrera recently surpassed the 450-homer mark, so he’s now looking at 49 more to reach Club 500. Doubtful he reaches that milestone, but fantasy owners can relish in the fact that a hot Miggy means he’ll finish the season with another career milestone well within reach. He’ll also hit this other milestone soon enough as he needs just three extra-base hits to join the other 38 major leaguers who have reached that plateau. With a strong showing the rest of the way, it seems likely that the Tigers first baseman will find himself in the top-30 among those extra-base hit leaders. The slow start has plenty of fantasy owners nervous that Cabrera, who continues to succumb to minor injuries, is going to see the bottom fall out at some point, but confidence should remain high. Watch how June turns out for him. One good month could easily push his numbers back to his normal elite status.

Robinson Cano – 300 HR, 500 doubles

He looks as dialed-in as anyone right now and his 10 doubles and 10 home runs this season put him just 12 homers shy of 300 and 11 doubles shy of 500. Currently 72nd on the doubles list, Cano should easily reach the 500 level which will push him into the top-60 of all-time doubles leaders and when he reaches both milestones, he’ll join a very elite group of just 34 players who have achieved both. The real question for fantasy owners is whether or not he can reach both plateaus by the All Star break. His slow April still saw six doubles and four home runs, so if he can continue to carry May’s momentum into June and the first week of July, it’s going to be close.

Curtis Granderson – 300 HR, 300 doubles

With four home runs and 13 doubles so far this season, the Grandy Man is now just three shy of each milestone. The group isn’t as elite as the one Cano is about to enter, but Granderson will be the 120th member of the 300 HR, 300 doubles club and that’s still pretty damn impressive. The fact that he’s so close to both means we’ll easily see it this year, barring injury, but we would be remiss if we didn’t discuss the potential for a decrease in plate appearances once Yoenis Cespedes returns. Michael Conforto has certainly pushed his way in and unless Grandy is going to return to centerfield, the Mets are going to have to juggle three corner outfielders for two spots. Granderson has always been a streaky hitter, so anything of a platoon nature could increase those cold spells, for sure. Keep a watchful eye for when (or maybe I should say if) Cespedes returns.

Other interesting milestones to watch out for:

Kris Bryant needs just 24 home runs to reach 100 for his short career.

Jose Reyes needs just six stolen bases to reach 500.

Ryan Braun needs eight home runs to reach 300.

Dustin Pedroia needs just 17 more RBI to reach 700 for his career.

Adrian Gonzalez is 11 hits away from reaching 2,000.

Francisco Rodriguez needs just 13 more saves to reach 450.
