Through four starts in June, Tampa Bay Rays pitcher Shane Baz has been impeccable with Triple-A Durham. He's thrown 18 innings, with a 1.00 ERA, 1.22 WHIP, and 28:8 K/BB ratio. His fastball is reaching the upper 90s and his breaking balls have been electric. When he'll be promoted to the Rays' rotation hasn't been announced, but it should only be a matter of time before he's back in the big leagues. If one of the team's starters has to miss any time, Baz should be first in line to take their place. Overall, he's worthy of holding onto in most leagues.

The St. Louis Cardinals are hopeful that third baseman Nolan Arenado (forearm) will be able to avoid a stint on the injured list while dealing with left forearm nerve irritation, according to manager Oliver Marmol. Arenado has been battling the issue for some time but he reported feeling better on Monday, and the team hopes he can return to the lineup by the middle of the week. The 33-year-old All-Star is missing a second straight game on Monday against the visiting Atlanta Braves. Veteran Brandon Crawford is making another start at the hot corner and is batting eighth against Braves rookie right-hander Spencer Schwellenbach. Crawford has become a backup at this point in his career and is a poor DFS choice near the bottom of the lineup. He's also hitting just .196 (9-for-46) in his first year in St. Louis with a homer and three RBI.

St. Louis Cardinals pitching prospect Quinn Mathews has been promoted to Double-A Springfield. The 23-year-old lefty has been incredible through 74 1/3 innings, this year. With Low-A Palm Beach, he posted a 1.47 ERA, 0.82 WHIP, and 52:11 K/BB ratio in 30 2/3 innings. With High-A Peoria, he posted a 2.68 ERA, 0.76 WHIP, and 58:9 K/BB in 43 2/3 innings. Mathews was drafted out of Stanford in the fourth round of last year's draft. Currently the Cardinals' No. 20 prospect (per MLB.com), he's expected to make his MLB debut in 2025.

Los Angeles Dodgers outfielder Teoscar Hernandez is out of the starting lineup ahead of Monday's game against the Chicago White Sox. There is no injury being reported, so it's assumed that this is a routine rest day for Hernandez. It is a bit odd to see Hernandez getting a day off against a left-handed starting pitcher. Regardless, Hernandez will sit out with Jason Heyward and Miguel Vargas covering the corner outfield spots on Monday.UPDATE: Hernandez is in the Dominican Republic for personal reasons and is expected to rejoin the team in Chicago on Tuesday.

Los Angeles Angels starting pitcher Patrick Sandoval (elbow) is expected to undergo season-ending surgery. The southpaw was recently placed on the injured list due to an elbow issue. After further testing, Sandoval was found to have a torn UCL and will likely need Tommy John surgery. If that happens, Sandoval probably won't be able to pitch again until the middle or late next season. He wasn't much of a fantasy option this season with a 2-8 record and 5.08 ERA in 16 starts. The Angels have recalled another starter yet, so we'll have to wait and see what they do with Sandoval's spot.
