Boston Red Sox pitching prospect Richard Fitts is expected to make his first start of the season on Sunday against Jacob deGrom and the Texas Rangers. The 25-year-old earned the fourth spot in the rotation this spring after allowing four earned runs in 14 2/3 innings pitched (2.45 ERA) on 13 hits and six walks while striking out 14. The righty made his MLB debut last season for the Sox, pitching to a 1.74 ERA and 1.26 WHIP over 20 2/3 IP, albeit with just a 7:9 BB:K. The former sixth-round draft pick has shownsolid command in the minors but has seen diminishedstrikeouttotals at each level on his ascent to the majors, so while he may end up being a decent real-life pitcherfor the Red Sox, there isn't much fantasy appeal here outside of deeper leagues.

The San Francisco Giants have added infield prospect Christian Koss to their Opening Day roster. The 27-year-old was a non-roster invitee to camp this spring, but had a strong spring that prompted the Giants to retain him on the roster to begin the year. The right-handed hitter went 14-for-41 (.341) with a home run, five RBI, 12 runs scored, and a stolen base in Cactus League play, along with a 5:7 BB:K. The former12th-round draft pick owns a career .274/.339/.454 slash line in the minors with about average walk and strikeout rates. Koss will be one of theGiants' bench bats who will be making his MLB debut whenever he gets into a game, but there's not a whole lot here to get excited about for fantasy, and he can be safely left on the waiver wire for now.

Milwaukee Brewers pitching prospect Chad Patrick has made the team's Opening Day roster. Patrick was optioned to Triple-A earlier in March, but with pitchers DL Hall and Tobias Myers dealing with injuries and Brandon Woodruff not quite ready, Milwaukee found itself in need of pitching help. The righty showed enough command and strikeout potential this spring to earn a spot on the roster. Despite allowing five earned runs on 13 hits over eight-and-one-third innings of work, the former fourth-round pick walked just one batter and struck out 10. Whether he makes a start early on or comes on in relief, whenever he takes the mound it will be his MLB debut. The 6-foot-1 hurler pitched well at Triple-A last season, recording a 2.90 ERA, 1.09 WHIP, and a 19.1 percent K-BB% over 136 1/3 IP, but he may be more of a DFS play if he earns a spot start rather than a waiver add.

The Washington Nationals optioned pitching prospect Jackson Rutledge to Triple-A Rochester on Wednesday after a spring that saw him post a 3.00 ERA, 1.33 WHIP, and a 10:14 BB:K in 15 innings of work. The righty had moved to the bullpen earlier in the month in hopes of unlocking some extra velocity and effectiveness, but the move wasn't enough to helphim stick with the big league club. The 6-foot-8 hurler has made a handfulof startsfor the Nationals over the lastcouple of seasons, but it remainsto be seen whether he'll stay in the rotation at Triple-A or fill a relief role. Regardless, until he's back in the big leagues pitching meaningful innings, the former first-round draft pick is not relevant for fantasy.

San Francisco Giants catcher Tom Murphy (back) will miss at least the first two months of the season after landing on the 60-day IL to start the season. The veteran was limited to just 13 games with the Giants last year due to a sprained MCL, but he was expected to be in the mix as a backup option behind Patrick Bailey this season. He dealt with back spasms early in training camp and was diagnosed with a middle-back disk herniation. With Murphy out for a while, Sam Huff will serve as the Giants' primary backup catcher to start the season after beating out Max Stassi, who will start the season in Triple-A. Huff hit .313 with two home runs and a .444 wOBA in his 15 spring training games.
