Jose Berrios is racking up strikeouts at a rate not seen in Minnesota in nearly a decade.
The 24-year-old All-Star reached 300 career K's last week, 18 starts into his third season and 57 starts into his young career.
He's now the fifth-fastest Twins starter to reach the milestone, tied with Jim Merritt, who spent four seasons with the Twins in the late '60s.
Dave Boswell, Francisco Liriano, Johan Santana and Bert Blyleven are the only Twins pitchers to get to 300 faster. It took Boswell, Liriano and Santana four seasons to reach 300, while Blyleven reached it in just two.

Other notes:
-- Twins outfielder Max Kepler, himself a lefty, had a .453 OPS against left-handed pitching a year ago, but has a .900 OPS against southpaws so far this season. It's the largest such increase for a left-handed batter since 1978.
-- The Twins open a three-game series with the Kansas City Royals on Monday night. Third baseman Mike Moustakas leads the Royals in RBI (56), runs (39) extra-base hits (36) and home runs (17). Only four other players are currently leading their respective teams in all four categories.
-- Royals catcher Salvador Perez has been extremely productive in Minneapolis over the years. He's hitting .349 with a .993 OPS in 209 career at-bats at Target Field, both his highest in an American League ballpark.
-- Twins first baseman Joe Mauer has swung at the first pitch just 3.3 percent of the time this season. If the season ended today, it would be the second-lowest first-pitch swing percentage on record since the league began tracking the stat in 1988.
