Arizona Diamondbacks left-hander
Joe Mantiply will get the "start" for Game 4 of the World Series on Tuesday against the visiting Texas Rangers. He'll be opposed by left-hander
Andrew Heaney. Mantiply will merely be serving as the opener in what is expected to be a bullpen game for the Diamondbacks as they look to even the series back up at two games apiece. The 32-year-old southpaw struck out one in a scoreless inning of work in Game 1 of the World Series on Friday. He has allowed four runs (three earned) on five hits while walking three and striking out five in 6 1/3 relief innings in this year's postseason. Right-hander
Ryne Nelson is the best bet to see the bulk of innings in relief for the Snakes on Tuesday evening.

Arizona Diamondbacks left-hander
Joe Mantiply will make the start in Game 4 of the National League Championship Series on Friday against the visiting Philadelphia Phillies in what will be a bullpen game for the D-backs staff. Mantiply will get another shot at the Phillies after allowing three earned runs on three hits while walking two in just one-third of an inning in the Game 2 loss in Philadelphia on Tuesday. In his first three career playoff outings this year, Mantiply threw 2.2 scoreless innings of relief with one walk and two strikeouts. The 32-year-old southpaw should not be started in DFS, as he's likely to go an inning or two on Friday, at the most. Right-hander
Ryne Nelson could pitch the bulk of the innings in this "bullpen" game.

The Arizona Diamondbacks have fielded offers from opposing teams for left-handed pitchers
Andrew Chafin and
Joe Mantiply, per Ken Rosenthal of The Athletic. Chagin has made 43 relief appearances this season, posting a strong 3.13 FIP while maintaining a career-high rate of 12.84 K/9. The 33-year-old, who relies heavily on his sinker and slider, is making $6.25 million this season and comes with a club option for 2023. Meanwhile, Mantiply, 32, is controllable through 2026, making him a more intriguing option for teams with a longer-term focus. He has tossed 15.2 innings this season, racking up a 3.23 xFIP, 8.04 K/9, 0.57 BB/9, and 53.2 GB%. Both players are solid bullpen contributors and could give an extra boost to contenders should Arizona choose to trade them.

The Arizona Diamondbacks reinstated left-hander
Joe Mantiply (shoulder) from the 15-day injured list on Tuesday and optioned right-hander
Luis Frias to Triple-A Reno in a corresponding move. Mantiply should return to a high-leverage role in Arizona's bullpen after needing some time to recover from left shoulder fatigue. The 32-year-old southpaw will be making his 2023 season debut when he gets into a game. He was a first-time All-Star in 2022 in his fifth year in the big leagues. Mantiply was impressive with a career-best 2.85 ERA (2.83 FIP), 1.08 WHIP, two saves, six walks and 61 strikeouts in 60 innings over 69 relief appearances. He has value in fantasy leagues that count holds.
