Here's a look at top prospects to watch in today's Minor League action:
Hitter to watch: Ian Happ (Cubs' No. 2, No. 26 overall), Iowa at Oklahoma City (12:05 p.m. ET on MiLB.TV)
Happ's homer on Sunday, a solo blast in the sixth off former Major League All-Star Jair Jurrjens, gave him three straight games with a round-tripper. The second baseman has already totaled 13 bases and scored five runs through his first 15 at-bats of the season for Triple-A Iowa, following up a strong 15-homer, 73-RBI season between Tennessee and Myrtle Beach last season.
Pitcher to watch: Jay Groome (Red Sox's No. 3, No. 39 overall), Greenville vs. Lexington (7:05 p.m. ET on MiLB.TV)
Groome, the 12th overall pick by Boston in last June's MLB Draft, is set to make his full-season debut after making two starts in the rookie Gulf Coast League and one start for Class A Lowell last summer. The southpaw may be handled carefully early in the year, but Red Sox fans will be eager to see what he can do for Greenville.

Duel of the day: Francis Martes (Astros' No. 1, No. 19 overall) vs. Frank Duncan (D-backs' No. 24) Fresno vs. Reno (9:35 p.m. ET on MiLB.TV)
Martes' name was floated around in the Astros' trade rumors surrounding White Sox ace Jose Quintana, but Houston likes what it has in the big right-hander. Martes fared well in Arizona Fall League action last fall, posting a 3.22 ERA and 10.1 strikeouts per nine innings over six starts.

Duncan was traded from the Pirates to the D-backs' organization hours before pitchers and catchers were set to report for Spring Training. The right-hander is looking to build on a career year in which he went 12-8 with a 2.34 ERA between Double-A Altoona and Triple-A Indianapolis and earned a trip to the Triple-A All-Star Game.
