Sunday's scouting report: Pirates at Marlins
• After struggling to generate swings and misses last year with the Twins — when he posted an anemic 3.9 whiff rate — Worley has demonstrated more bat-missing ability in Triple-A this season, striking out 43 in 46 innings. It's a simple formula for Worley: get ahead with the fastball and try to generate weak contact and swings and misses with his changeup.
• The Pirates are the ninth-best fastball hitting team in the majors, according to Fangraphs.com. Henderson Alvarez, like Nathan Eovaldi, who the Pirates roughed up on Friday, is a fastball-heavy pitcher. Alvarez sits in the mid 90s with both a four- and two-seam fastball. Alvarez has improved his control and is walking just 1.8 batters per nine innings, so it's perhaps a game where the Pirates will be more aggressive early in counts.
Nick Kingham might be the next Pirates' prospect to keep an eye on. Kingham made his first Triple-A start on Friday and struck out eight over seven shutout innings.
