The Giants named Landen Roupp their fifth starter to begin the season, manager Bob Melvin tells reporters (link via Alex Pavlovic of NBC Sports Bay Area). Hayden Birdsong, who was the remaining competitor for that spot, also made the team but will start the year in relief.

Roupp breaks camp for the second straight year. The righty pitched mostly out of the bullpen during his rookie season. He started four of 23 appearances and tallied 50 1/3 innings of 3.58 ERA ball. Roupp’s 21.7% strikeout percentage and 47.2% grounder rate were close to league average. A 12% walk rate was the main red flag, but he has thrown plenty of strikes this spring.

The 26-year-old Roupp only walked one of the 46 batters he faced in camp. He hit a couple batters as well but only put 6.5% of batters faced aboard for free. Roupp struck out 14 while surrendering eight hits and five runs through 12 innings. That earns him his first Opening Day rotation spot behind Logan Webb, Justin Verlander, Robbie Ray and Jordan Hicks.

Birdsong had an even more impressive Spring Training. The 6’4″ righty ran an 18:0 strikeout-to-walk ratio over 12 innings of one-run ball. He could hardly have pitched better, but he’ll work in relief for the first time since his 2022 draft year. Birdsong started all 16 MLB appearances after earning his first major league call last June. He turned in a 4.75 ERA through 72 innings. Birdsong punched out nearly 28% of opposing hitters but walked 13.7% of batters faced. It’s been a similar pattern throughout his minor league career. The Eastern Illinois product has a 34.4% strikeout rate against a 13.7% walk percentage in the minors.

Kyle Harrison entered camp as the favorite for the fifth starter role. The Giants optioned him to Triple-A Sacramento over the weekend, in large part because a virus delayed his ramp-up this spring. They could have optioned Birdsong as well, but his exhibition performance was so loud that he left the team little choice but to carry him on the MLB roster in some capacity. Pavlovic writes that the Giants will use Birdsong in multi-inning appearances to keep him stretched out. There’s a good chance he’ll get a rotation opportunity before long as injuries arise throughout the season.
