Joe Mantiply's Quiet Inning Not Enough in Loss

Joe Mantiply allowed one hit in a clean inning during Monday's 6-4 loss to the Dodgers.

Fantasy Impact

Despite not allowing any runs, Mantiply failed to record a strikeout, contributing to a rather uneventful outing. With a season ERA now sitting at 4.42 and a WHIP of 1.31, his performance this year has been less than stellar for fantasy managers. His low strikeout rate of 6.9 K/9 continues to limit his upside in formats that reward strikeouts heavily.

Joe Mantiply Seals the Deal Against Reds

Joe Mantiply notched a save in the Diamondbacks' 4-3 victory over the Reds.

Fantasy Impact

He threw 11 pitches, striking out one without allowing any hits or walks in his brief appearance. This performance marks Mantiply's second save of the season, bringing a slight uptick to his save tally which could hint at more late-game opportunities. His solid 3.52 ERA and 1.17 WHIP are respectable, but his moderate strikeout rate of 7.6 K/9 doesn't make him a standout for those chasing strikeouts. However, his excellent 2.34 FIP suggests he's pitching better than some traditional stats might indicate. Fantasy managers should view Mantiply as a potential low-end relief option, particularly in formats that reward holds and saves, though his limited strikeout capability somewhat caps his upside.

Joe Mantiply (shoulder) nearing return

Joe Mantiply is nearing his return from a shoulder injury.

Fantasy Impact

Mantiply will pitch in a rehab assignment Tuesday in Double-A Amarillo. He has been sidelined since the start of the season due to "shoulder fatigue." “The bullpens, the live BPs that he's thrown, everything's ticked up and he's feeling very, very good,” manager Torey Lovullo said. “Whether it was timing, whether it was just the dead arm, it was something that just wasn't right and I think the rest has done him well.” He should have a big role in the Diamondbacks bullpen when he is healthy.

Joe Mantiply picks up second save of the season in win over Marlins Tuesday

Arizona Diamondbacks RP Joe Mantiply pitched the final inning on Tuesday, with zero strikeouts, no walks, and no hits allowed in the Diamondbacks 5-4 win over the Marlins.

Fantasy Impact

This save opportunity for Mantiply was more of a higher leverage spot than it should have been as the Diamondbacks held a 5-run lead before another reliever out of the bullpen blew it nearly in one inning. The relief pitcher does not warrant fantasy consideration due to the low save numbers and low strikeout numbers.
