J.D. Martinez started this season in the minors and was pulled from a game earlier this week when he swung at a pitch too early in the count. Yet he's started five straight games for the Astros, with one home run and a .273 batting average on the year.
And if you just look at Martinez' last five games, he's even more attractive, with a .316 average, .826 OPS, home run, and five RBI during that span.
Martinez was a hot add last year, before fizzling in early May, being optioned back to the minors and eventually finsihing the year with a .241 average. But he has a stellar track record in four minor-league seasons (a career .334 average and .929 OPS with 43 home runs and 95 doubles in 321 games) and looks like he's a starter in the wide-open Houston outfield.
I wouldn't overreact to Martinez, but in a 16-team Roto league, he could make for a decent fifth outfielder -- high average with some minor power potential and RBI hope -- at a cheap price, especially this early in the season.
Owned in just three percent of leagues, Martinez should at least be grabbed in most AL-only formats.
