I can't stop looking at Matthew Holliday back in his Colorado Rockies uniform. Matt Holliday! With the Rockies again!
When Holliday first suited up for Colorado on Thursday, it was the first time he'd worn that particular shade of purple in a big league game in nearly a decade. Look how he used to look:

Adorable! When Holliday homered on Saturday -- against one of his other old teams, the Cardinals -- it was his first homer for the Rockies since Sept. 12, 2008, a span of 3,635 days. The homer, which gave the Rox the lead in the only game they'd win last weekend, was as pretty as any of the 128 other homers he hit for Colorado.
Seeing Holliday back in his old Rockies jersey just looks right, and I want to see more of it. He's just one of many veteran players who, before their careers wind down entirely, we'd love to see back in their original team's uniform. That warm feeling you get when you see Holliday with the interlocking CR? Here are some other reunions that would give you that same feeling.
Jose Bautista, Toronto Blue Jays
Bautista has made an odd little tour of the National League East this season -- between New York, Atlanta and Philadelphia, it must be confusing for fans to figure out when they're supposed to boo him -- but of course he is and will always be a Blue Jay. (Though remember he was a light-hitting Oriole and Pirate first.) Someday they really should put up a statue of Bautista's bat flip from the 2015 American League Division Series in Toronto, but it'd be nice to see him get one last go-around up north before hanging up the spikes. For what it's worth: He showed he still had a little pop with the Mets this year.

David Freese, St. Louis Cardinals
Freese has been gone from St. Louis for five seasons, and he still gets standing ovations every time he comes to the plate as an opposing player. (The Pirates are at Busch Stadium this week, and he's surely got another one coming.) That's what happens when you grew up in St. Louis and are personally responsible for two of the greatest moments in franchise history. Freese has very quietly put together his best offensive season since he made the All-Star team in 2012, so even though he's now 35 years old (!), he's far from done. Cardinals fans were elated to see Matt Adams return to the team this week. Imagine what would happen if Freese returned.

Zack Greinke, Kansas City Royals
It has been so many years since Greinke left Kansas City, and he has pitched for so many teams (four) since, it's easy to forget he was once the Royals' most exciting prospect since George Brett (or maybe Carlos Beltran). He also won his one American League Cy Young Award there. The Greinke Era and the Moustakas/Perez/Gordon/Hosmer/Cain Era never quite overlapped; Greinke pitched for Kansas City for seven losing seasons and then left right when the talent base that would end up reaching two consecutive World Series and winning one was starting to mature. He might as well come back and finish his career as the next generation of young Royals players (whoever they might be) are starting their own ascendance. Greinke will next be a free agent in 2022. Maybe Kansas City will be good by then.

Evan Longoria, Tampa Bay Rays
Sure, Longoria has only been gone one year, but we're still talking about the greatest player in Rays history (by a large margin), the kid who won the AL Rookie of the Year Award the season Tampa Bay went to its lone World Series, the star who hit the homer run that sent them into the playoffs on the last day of the regular season in 2011. Longoria, for all intents and purposes, is the Tampa Bay Rays for a lot of people, and probably always will be. He's somehow only 32 years old, so he's got plenty of time to get himself back to St. Petersburg someday. If they ever get a new ballpark, having Longoria back on the team that opens it doesn't sound like the worst idea in the world, does it?

Andrew McCutchen, Pittsburgh Pirates
Pirates fans lost their mind for Cutch when he came back just a few months after he was traded, so they'll obviously hold him close and dear if he ever put the Bucs jersey back on. McCutchen is going to be a fascinating free-agent case this offseason, but it seems unlikely he'll sign such a long contract with a team other than the Pirates that will go on too far for him to return to Pittsburgh someday. He, as much as anyone on this list, will never quite look right in other uniform than that one.

Jose Pujols, St. Louis Cardinals
So this would be quite the reunion. When Pujols left the Cardinals, famously signing a 10-year "services contract" beyond the 10 years he would play for the Angels, such a return from Albert to St. Louis would have seemed unfathomable. But hearts have softened on both sides over the years, and much of the animosity of the time has dissipated. The thaw may be completed next June, when Pujols (assuming he is healthy) at last makes his long-awaited return to Busch Stadium with the Halos. He'll get the massive ovation due to him, and one he might not have had the Angels returned in 2012. And who knows, maybe it potentially cracks the door a bit for a final-season cameo with the team Pujols built his Hall of Fame career with. No one else will ever wear No. 5 for the Cards other than him. Pujols might as well put it on one more time.

Justin Verlander, Detroit Tigers
Verlander came so close to winning a World Series with the Tigers, but it required him heading to Houston to finally get one. (And maybe more than just one.) But he'll be a Tiger for all time, and he and that city are so closely tied that if he makes the Hall of Fame, it'll obviously be in a Tigers cap. Verlander has two more seasons on his contract with Houston, but he'll still have plenty in the tank in 2020. The Tigers might not be quite ready to compete yet by then, but that's OK: Verlander will probably pitch past his 40th birthday anyway. Whenever they're ready, he will be.
