The San Diego Padres finally decided to hit the reset button on Hunter Renfroe, sending the struggling Mississippi State product back to the minors on Saturday. Renfroe, a highly touted prospect and the Padres’ opening day right fielder, has experienced many peaks and valleys this season. To wit: 20 home runs and 24 doubles with a .230 average, 125 strikeouts and 26 walks. “Sometimes it’s the absolute best thing you can do for a guy,” Padres manager Andy Green told the San Diego Union-Tribune. The Padres also want Renfroe to work on his defense while at Triple-A El Paso. It’s unclear whether Renfroe will return to the big league club in September, when rosters expand. P.S. There already has been a lot to absorb in the MLB Transactions page this weekend. On Friday, St. Louis recalled ex-Ole Miss star Mike Mayers from Triple-A Memphis. He pitched that night against Pittsburgh, yielding four earned runs in 2/3 of an inning, and then was optioned back to Memphis on Saturday. Thanks for playing. … Detroit recalled Richton’s JaCoby Jones from Triple-A Toledo on Friday. Jones, who was the Tigers’ opening day center fielder, started on Saturday and went 1-for-2, “boosting” his average to .151 in 23 MLB games spread over three stints with the Tigers this season. Jones was scuffling before he was hit in the face by a pitch in late April and sent back to the minors. He was hitting .243 with nine homers and 12 steals for Toledo. … Former Picayune High star T.J. House was called up by Toronto on Saturday. The left-hander, 5-7 with a 4.44 ERA in 27 games for Cleveland from 2014-16, was 9-11, 4.72 at Triple-A Buffalo. … Also on Saturday, Seattle placed Southwest Mississippi Community College alum Jarrod Dyson on the 10-day disabled list. Dyson was hitting .340 this month and is at .255 with 28 stolen bases, 56 runs and 30 RBIs in 109 games on the season, his first with the Mariners.
