Friday's scouting report: Pirates at Cubs
• With top-of-the-rotation arms Gerrit Cole and Francisco Liriano on the DL, Charlie Morton has stepped up his performance at critical time. Morton has posted back-to-back quality starts and has allowed two earned runs or fewer in five straight outings. Coinciding with Morton's improved performance is an improving ground ball rate. Morton is averaging 3.33 ground balls per fly ball in June compared to a 2.42 ratio in May and 2.06 in April.
• The enigmatic Edwin Jackson has allowed 10 runs over 10 2⁄3 innings in his past two starts. Jackson has posted his highest fly-ball rate since 2009, which can be dangerous in Wrigley Field depending upon wind conditions.
When Neil Walker returns to the lineup, possibly next week, a platoon situation could emerge at third base with Josh Harrison getting work against left-handed pitchers. Pirates manager Clint Hurdle said he plans to give Harrison regular playing time, but he'll have to become creative in lineup construction.

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.
We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.
We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.
