2023 Fantasy Outlook
Wacha joined Boston on a one-year, $7 million deal for 2022, and he delivered a 2.70 ERA before he surrendered 11 runs in his final two starts of the campaign. He was limited to 23 starts (127 innings) due to a shoulder injury but still compiled an 11-2 record, and it was a major bounce-back effort after he posted a 5.11 ERA across the previous three seasons. He cut his HR/FB rate nearly six percentage points to 12.4 percent from that three-year stretch, and he also reduced his hard-hit rate (35.4 percent) more than four percentage points. However, Wacha also had a 4.56 xERA in 2022, so there's reason to be worried about some regression. He'll turn 32 years old in July and should be able to secure a rotation spot somewhere in free agency, but his fantasy potential could vary significantly depending on where he lands. Wacha's season-to-season inconsistency through his career also provides pause on whether to expect a repeat performance in 2023. Read Past Outlooks

Cruises to victory
Wacha (13-4) yielded two runs on six hits and a walk over seven innings Sunday, striking out six and picking up a win over St. Louis.
ANALYSIS
Wacha rolled through six shutout frames before the Cardinals finally broke through with two runs in the seventh inning. The Padres had already provided 12 runs of support before then. Wacha earned his second straight win and lowered his season ERA to 3.39 across 127.1 frames. However, he owns a 5.54 ERA in five September outings. Wacha is projected to close out his 2023 season with a road start against the White Sox.

Wacha was much the same pitcher in 2021 that he was the year previous. An inflated 5.05 ERA belied more advanced metrics like xFIP (3.91) and SIERA (4.00); however, there is another story to tell. Opponents barreled his offerings at a greater rate and increased exit velocity against the right-hander. Enter the Red Sox, the fourth team in the last four years that will attempt to reverse a worrisome trend. The pitcher himself vowed to make changes, ditching a cutter that had been his third pitch, in addition to a four-seamer and changeup, in favor of throwing his curveball more often. The results were promising over his final eight appearances in 2021, and Wacha won the fourth-starter job for Boston, which is expected to have an offense to support the 30-year-old Wacha.
