Rotation plans up in air due to off days, expectant wife, Andrew Heaney (?)

CHICAGO -- Nathan Eovaldi's wife is due to deliver any day. Andrew Heaney turned in yet another strong pitching performance Saturday in the minors. And the Marlins don't play on Monday or Thursday.

Add it all up, and the Marlins aren't entirely sure how their rotation will shape up this coming week. Or they're sure and they're not telling anyone.

Here's what we do know: Tom Koehler will start Tuesday at Texas. Beyond that, questions marks.

Jacob Turner is listed on the team's daily info sheet as Wednesday's starter, and he threw his normal between-starts bullpen this morning at Wrigley. But manager Mike Redmond also told reporters that Eovaldi could also start on Wednesday depending on the status of his wife, who is expecting their first child. With the off day, Eovaldi would be pitching on normal rest if he goes Wednesday, even though he would vault in front of Turner.

Throw in the fact that it's now possible for the Marlins to safely call up Heaney from Triple A New Orleans without risking Super 2 status, and it muddles the picture even further.

Heaney went six innings Saturday for the Zephyrs, allowing a run on five hits over six innings. He struck out nine while walking one. He has now made four starts for New Orleans, going 3-0 with a 2.74 ERA. Overall this season, he is 7-2 with a 2.47 ERA while striking out 79 in 76 2/3 innings

And then there's this: once the inevitable occurs and Heaney is promoted, it would only seem natural -- given their history last season with Jose Fernandez -- that they'll limit the left-hander's pitch count. Fernandez was shut down in September after throwing 172 innings. Heaney totaled only 95 innings last season, so he'll eventually be entering uncharted territory in terms of his total workload.

If the Marlins decide to promote Heaney now, he could start either Friday or Saturday after the Marlins return home from their road trip. If they decide to give him another start at Triple A, he would likely come up in the Mets series at home.

Don't look for Emilio Bonifacio to take the Marlins deep today the way he did  Saturday when he parked one in the Wrigley Field bleachers off Randy Wolf. Not if the wind continues blowing in the way it is at the moment. The flags are blowing straight in, and they're bringing cool weather. Players are wearing hooded sweatshirts while taking batting practice in an attempt to keep warm.

Both teams will be wearing throwback uniforms this afternoon. The Marlins will wear replica uniforms worn by the minor league Miami Sun Sox of the 1940s and early '50s. The uniforms are rather non-descript, with simple black lettering spelling out "MIAMI" across the front. The caps are black with a block "M."
