• The D-backs are the only team in baseball with more one-run wins (26) than the Pirates (23). More than 58 percent of Arizona's games (69 of 118 going into Thursday) have been decided by two runs or fewer and they are 40-29 in those games.
• Pedro Alvarez and Paul Goldschmidt entered Thursday's games tied for the National League lead in home runs with 29. Goldschmidt has already set a club record for home runs by a Diamondbacks first baseman in a single season, while Alvarez needs one more to match his career high, set in 2012.
• The Pirates went into their series at Arizona on April 8 with a 1-5 record and since then have accumulated the best record in baseball at 70-44. The Pirates won two of three games at Chase Field but the D-backs have won three of the past five games in Pittsburgh and are 29-22 all-time at PNC Park.
TribLive commenting policy
You are solely responsible for your comments and by using TribLive.com you agree to our Terms of Service.
We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.
While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.
We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers.
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.
We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
