Jake Arrieta (shoulder) has been throwing from flat ground as he works toward getting back on the mound.

Arrieta has dealt with some tightness in his throwing shoulder that's put him behind schedule in the early part of spring. Last week he believed he was close to getting back on the mound, but his shoulder hasn't progressed to that point yet. Even if he's not ready for the start of the season, the 27-year-old should join the Cubs' rotation at some point in April.

Arrieta held a 3.66 ERA, 1.12 WHIP and 37 strikeouts in 51 2/3 innings last season after arriving via trade from the Orioles.

The Cubs have several rotation candidates in camp, but they were hoping for a smooth spring from the 27-year-old Arrieta, who posted a 3.66 ERA, 1.12 WHIP and 37 strikeouts in 51 2/3 innings last season after arriving via trade from the Orioles.

Jake Arrieta pitched six innings of one-run ball for a victory over the Pirates on Wednesday.

Arrieta had to wait his turn after getting picked up from the Orioles, but he ended up 4-2 with a 3.66 ERA in nine starts for the Cubs. He should be pretty much assured a 2014 rotation spot, and he'll be a nice sleeper in NL-only leagues after getting out of the harsh AL East.

Jake Arrieta fired seven innings of one-run ball in Thursday's 5-1 win over the Brewers.

Arrieta held the Brewers to three hits and one walk while striking out five. The lone run scored on a solo home run from Carlos Gomez in his final inning of work. The 27-year-old now has a respectable 3.94 ERA over eight starts since joining the Cubs, though his 36/22 K/BB ratio over 45 2/3 innings leaves something to be desired. He'll square off against the Pirates next week.

Arrieta will carry a 5.63 ERA, 1.44 WHIP and 54/38 K/BB ratio into Thursday's start against the Brewers in Milwaukee.
