The Giants have placed right-hander Jeff Samardzija on the 10-day disabled list with inflammation in his pitching shoulder, Kerry Crowley of the Bay Area News Group was among those to report. Infielder Kelby Tomlinson is up from Triple-A Sacramento in a corresponding move.

This is the third DL stint of the season and the second on account of shoulder troubles for Samardzija, who was known for his durability entering the year. The 33-year-old came into 2018 fresh off five straight seasons of 200-plus innings. He has only thrown 44 2/3 at the halfway point this year, though, and hasn’t been effective when healthy enough to take the hill.

Samardzija has pitched to a 6.25 ERA/5.42 FIP thus far, thanks in part to poor strikeout and walk rates (6.04 K/9, 5.24 BB/9), a 29.9 percent groundball mark and a recent stark decline in velocity. All of those numbers represent personal-worst figures for Samardzija, who holds a 4.17 ERA/3.86 FIP with 8.1 K/9, 2.72 BB/9 and a 43.8 percent grounder rate for his career.

Samardzija is in the third season of a five-year, $80MM contract, a deal the Giants awarded him when he was a quality mid-rotation starter. Now, with a desire to stay under the $197MM competitive-tax threshold, they’d surely like to get rid of his money. The club has reportedly made him available, in fact, but his 2018 performance, newfound injury troubles and contract combine to make him immovable.

Despite Samardzija’s woes this year, the Giants sit a respectable 50-47, three games out of a wild-card spot and 3 1/2 behind the NL West-leading Dodgers. If Samardzija misses significant time after the All-Star break, it seems likely San Francisco will slot Derek Holland back into its rotation behind Madison Bumgarner, Johnny Cueto, Andrew Suarez and Dereck Rodriguez.
