Getting swept by the Mariners was certainly not the way the Angels wanted to end one of their better stretches of the season, but it also should not erase the progress the club made over the previous few weeks. Los Angeles showed signs of improvement on both the mound and at the plate during that run, and now they'll have an opportunity to respond against another tough opponent in the Red Sox. If the Angels hope to get back on track immediately, several key players could have a major impact on how the series unfolds.Jo Adell Has Enjoyed Success Against BostonOne player who could play a major role in this series is Jo Adell. Throughout his career, Adell has found success against the Red Sox, posting a .289 batting average and a .929 OPS. He also appeared to find his rhythm at the plate in June, hitting .264 with a .716 OPS during his best month of the season. With his confidence trending in the right direction and a favorable track record against Boston, Adell could be one of the Angels' biggest offensive contributors this series. If Los Angeles hopes to bounce back after being swept by Seattle, a productive series from Adell could go a long way toward helping the Angels regain momentum.Reid Detmers Looks to Build on a Strong JuneAnother player who could have a major impact on the series is Reid Detmers, who is scheduled to start the opener against Boston. The left-hander is coming off an outstanding month of June, posting a 2.27 ERA over 31.2 innings while striking out 30 batters. More importantly, Detmers consistently gave the Angels a chance to win more often than not when taking the mound, looking much more like the pitcher the organization envisioned. If he can carry that momentum into the series opener and deliver another quality start, the Angels will have an excellent opportunity to begin the series with a win and quickly put the disappointing sweep by Seattle behind them.Los Angeles Angels starting pitcher Reid Detmers (48) pitches to Milwaukee Brewers players in the bottom of the second inning Saturday, April 29, 2023, at American Family Field in Milwaukee.
