Timing is everything in fantasy baseball, especially when it comes to making trades. Strong managers know when to buy low, but the savvy, elite ones who know when to sell high.
Though it is tempting to hold onto a player riding a hot streak, long-term success often hinges on knowing when performance isn鈥檛 sustainable, or, in some cases, when history tells us a crash is inevitable.
Two of MLB鈥檚 biggest stars, Byron Buxton and Jacob deGrom, should be considered the biggest 鈥渟ell-high鈥 names right now.
Buxton is currently slashing .279/.345/.553 with 17 home runs and 13 stolen bases.
He is on pace for a 30-30 season, any fantasy manager鈥檚 coveted dream.
But if you鈥檝e rostered Buxton in the past, you know this ride doesn鈥檛 go on for much longer.
The Twins outfielder already has been on the IL twice this season, and we鈥檙e only at the halfway point. Over his 11-year MLB career, Buxton has played at least 100 games just twice. That isn鈥檛 a fluke, it鈥檚 a pattern.
The tools have never been the issue.
Buxton has always had elite power and speed, and his defensive value keeps him in the lineup when he is healthy.
But that鈥檚 the problem: He never stays healthy.
Even if you鈥檙e generally 鈥渋njury agnostic鈥 during draft season 鈥 a valid strategy given the randomness of injuries 鈥 it becomes a different calculation midseason, especially when a player鈥檚 past injuries have a clear and persistent track record.
Buxton is giving you first-round production at a mid-round cost. That is your signal. Package him in a deal for a more durable star 鈥 someone with less upside maybe, but far more week-to-week reliability. Your goal is to win in September, not reminisce about how great your roster looked in June.
Trouble is brewing in Texas as well. Jacob deGrom is back 鈥 sort of. He has a sparkling 2.08 ERA over 95鈥壜/鈧 innings, eight wins and is coming off a dominant June (1.41 ERA, 32 IP). But let鈥檚 be clear: These are borrowed innings.
He hasn鈥檛 topped 100 innings in a season since 2019, and we鈥檙e already approaching that threshold. His strikeout rate has dipped to its lowest since 2016, and though he still is striking out nearly a batter per inning, that slight erosion is a red flag. Velocity and command are still elite, but this version of deGrom is not indestructible.

Add in the brutal Texas summer and the Rangers鈥 likely playoff aspirations, and you鈥檝e got a situation that could go south quickly. Whether they start managing his workload or he hits another IL stint, the odds of him being a full-strength ace in September are slim. If you鈥檙e clinging to his past Cy Young-level performance, you鈥檙e ignoring years of recent evidence.
There is no shame in selling high. In fact, that is what separates championship teams from the rest. Don鈥檛 wait for the third IL stint or a late-August shutdown. Swap Buxton and deGrom for players who can carry you through the fantasy playoffs 鈥 while others deal with the fallout.
Trust the track record. Sell the hype. Win the league.
