Washington Nationals starting pitcher Foster Griffin has been one of the biggest surprises this season. Griffin returned to the big leagues this season after spending the last three years in Japan. He has been excellent and earned himself the first All-Star selection of his career in 2026. Through 19 starts, Griffin registered a 2.77 ERA, 1.01 WHIP, and a 109/26 K/BB ratio across 110.1 innings this season. The 30-year-old is showing no signs of slowing down, but fantasy managers shouldn't put too much faith in him. Dynasty managers especially should consider selling high on Griffin. Given his age and the level of success he's experiencing, it's likely only going to regress from here. He doesn't have much of a professional track record and has already thrown well over 100 innings this season. Griffin could still be a valuable fantasy asset, but him posting ace-type numbers in the long-term seems unlikely.

Milwaukee Brewers relief pitcher Trevor Megill didn't have an ideal beginning to the season. Megill was mainly used as a setup reliever early in the season, but he appears to have reclaimed the closer role in Milwaukee. Through 37 appearances, Megill owns a 3.00 ERA, 0.97 WHIP, and a 46/10 K/BB ratio with 14 saves. The right-hander earned a save in four of his last five appearances heading into the All-Star break. It seems that Megill has taken over as the full-time closer in Milwaukee, which is great for his fantasy value. Fantasy managers should expect Abner Uribe to be mixed in, but not as much as he was earlier in the season. Fantasy managers seeking saves should snag Megill where he's available.

Pittsburgh Pirates second baseman Brandon Lowe didn't get an All-Star nod, despite being well deserving of one. The 32-year-old is coming off a strong first half with the Pirates. Through 90 games, Lowe is slashing .246/.316/.487 with 21 home runs and 64 RBI. He smacked 31 long balls last season and has a good chance of surpassing that this season. Outside of the power, Lowe isn't offering a ton of upside to fantasy managers. The veteran slugger doesn't hit for average, walk much or steal bases at a high rate. Fantasy managers looking for help in the power department should hang onto Lowe, but he could be an interesting sell-high candidate.

St. Louis Cardinals starting pitcher Michael McGreevy will take the ball for the second half opener versus the Arizona Diamondbacks on Friday. The right-hander is well deserving of the No. 1 starter role after posting a strong first half of the season. Through 18 starts, McGreevy posted a 3.01 ERA, 1.10 WHIP, and a 66/23 K/BB ratio across 101.2 innings of work. The plan is for Dustin May to get the ball on Saturday, while Andre Pallante gets the series finale on Sunday. McGreevy didn't earn an All-Star nod, but could be a valuable fantasy asset in mixed leagues down the stretch of the season.
