De La Rosa collected his 16th hold of the season while tossing a scoreless seventh inning in Wednesday's 3-1 win over the Dodgers. Though he hit a batter for the second straight contest, De La Rosa has shown increased reliability in the late innings over the past couple of weeks, earning five holds and giving up just one run over 4.1 frames in his last eight appearances. With an unremarkable 4.37 ERA and 1.31 WHIP for the season, however, De La Rosa doesn't offer much interest in NL-only formats outside of leagues that count holds.
De La Rosa covered 1.1 scoreless innings of relief in Wednesday's 4-2 loss to the Mets. He walked a batter and struck out two during the appearance. De La Rosa has submitted a 4.97 ERA since the All-Star break, but it hasn't been enough to remove him from the setup mix, as he's still recorded four holds during that span. Still, it seems that De La Rosa would be best optimized as a LOOGY rather than a more traditional one-inning reliever, which is how manager Torey Lovullo has chosen to deploy him for much of the campaign. De La Rosa has limited left-handed hitters to a .175/.224/.290 line for the season, while righties have hit .268/.370/.455 against him.
De La Rosa struck out two and was credited with a hold in Friday's 2-1 win over the Giants after tossing a scoreless seventh inning. De La Rosa will presumably end up falling down a peg on the bullpen depth chart after the Diamondbacks acquired David Hernandez prior to the trade deadline, but the new pickup hasn't diminished in key spots thus far. The veteran lefty has recorded holds in his last two appearances, boosting his total to 11 on the season. De La Rosa is tied with Andrew Chafin for second on the team in that category, trailing only relief ace Archie Bradley (13).
De La Rosa tossed a scoreless sixth inning in Wednesday's 4-3 loss to the Reds in 11 innings, giving up a base hit and striking out a batter. With starter Zack Greinke running up his pitch count to 104 through five frames, the Diamondbacks required five relievers in the extra-inning affair, with De La Rosa receiving the first call out of the bullpen. He was able to keep the score knotted at 3-3 without too much trouble, ending a streak of three consecutive appearances where he had allowed a run. De La Rosa had been an integral part of the setup crew for the Diamondbacks earlier in the season, but it seems manager Torey Lovullo has since opted to deploy the lefty primarily in middle relief. Perhaps as a result of typically working earlier in games, De La Rosa has only collected two holds since the beginning of June.
De La Rosa gave up a base hit but recorded the final out of the eighth inning to earn his ninth hold of the season in Sunday's 4-3 triumph over the Rockies. De La Rosa's nine holds have him in a tie with Andrew Chafin for second on the team behind relief ace Archie Bradley (12). The 36-year-old's background as a starter and status as a left-hander make him a versatile weapon out of the bullpen for manager Torey Lovullo, but outside of NL-only leagues that count holds as a category, it will be difficult to wring much fantasy value out of De La Rosa.
