A year ago, Trevor Rosenthal presented a dilemma for owners on Draft Day. His first year as the Cardinals' full-time closer was a success with 45 saves and 87 strikeouts, but were his high walk rate and 1.41 WHIP worth the trouble? He cleaned up his control enough to rank third in Fantasy points and sixth in Rotisserie value among relievers, as he shrank his BB/9 ratio from 5.4 to 3.3. Because of the still-elevated walk rate, Rosenthal is a cut below the relief elite, but he should be drafted as one of the top 10 closers.
Rosenthal agreed to a one-year, $5.6 million contract with the Cardinals on Friday, avoiding arbitration. The right-hander will earn more than 10 times what he earned in 2015 in his first year of arbitration. Rosenthal is coming off a stellar season as the Cardinals' closer, with his biggest improvement coming in the form of a reduced walk rate, which he trimmed by more than two walks per nine innings. He was afforded a long leash by manager Mike Matheny and he remains secure in the role entering spring training.
Cardinals closer Trevor Rosenthal secured his 48th save in Monday's 3-0 victory over the Pirates, giving up one hit while walking and striking out a batter apiece in a scoreless inning. Rosenthal's save wasn't without its share of tension, as the closer began the frame by walking Andrew McCutchen and giving up a single to Starling Marte. The 25-year-old would settle down, however, retiring each of the next three batters to end the game. Rosenthal appears to be back on track following a disastrous four-run outing against the Brewers this past weekend.
Cardinals closer Trevor Rosenthal (2-4) took his second loss of the series Sunday against Milwaukee after blowing the save in the top of the ninth inning. He allowed four runs on a walk and two hits, without recording an out. Rosenthal loaded the bases immediately after entering in the top of the ninth before Jason Rogers delivered a pinch-hit grand slam to chase Rosenthal from the game. It was a rough weekend for Rosenthal, as he saw his ERA rise from 1.49 to 2.13 on the season.
Cardinals closer Trevor Rosenthal (2-3) took the loss Friday in a bullpen game, allowing one run on three hits across one innings in a 4-3 loss to the Brewers. Rosenthal came on in a tied game in the ninth and allowed three of his first four batters to reach against him--including a solo home run to Khris Davis--and then got a double-play to limit the damage. Rosenthal's 1.60 ERA seemed impossible to sustain, considering his xFIP is at 3.03. In any case, he is still one of the best closers in the league, saving 47-of-49 save opportunities this season.
Cardinals closer Trevor Rosenthal picked up his 44th save of the season Tuesday in the win over Milwaukee, allowing a hit and striking out a pair. Rosenthal now has 44 saves on the season, the fifth highest total in Cardinals' history. He needs four more over the final few weeks to grab the top spot. His secondary numbers (252 ERA+) all support that his 2015 season has likely been the best of any closer in Cardinals' history. Most promising is that Rosenthal is just 25 years old.
